My freezer was cold and my refrigerator was warm. I unplugged the unit, took apart the interior freezer panels and my coil was encased in a block of ice. I defrosted it put it back together and the next morning my freezer and refrigerator were both very cold.

I am going to go back in and test the heater, timer and thermostat but I have been unable to find any manuals for this model. It is a top freezer unit.

If someone could help me with the locations of the timer and the thermostat it would help me.

First remove the evaporator cover in the freezer so you can see the coils.
Do not let them de-ice.

Manually force a defrost cycle by turning the defrost timer cam (Item 53 in Section 5) till the fans and compressor turn off.
There is usually a hole in the cover to let you do this without taking anything apart. Looks like on your unit you may have to pop out the plug (Item 44 in Section 5)
Now check the defrost heater to see if it is on.
Be careful you do not want to burn your fingers.
If the heater is on then the timer needs replacing, re: it is probably stalling during it's rotation so is never getting into a defrost cycle.

If not on.
Unplug the unit.
Remove the wire for one side of the heating element (Item 37 in Section 7) from the wiring and measure it for continuity, usually around 20 ohms or so.

If the heater is OK
Remove one wire to the defrost thermostat (Item 43 in Section 7) (clipped onto the defrost coils) and measure it, should be 0 ohms when frozen. Note that it opens just above freezing so must be frozen to check it. Also inspect it, if it is bulged at all replace it even if it measures OK.

If both the above are OK then odds are the defrost timer contacts are toast.
Best way to test this is a live test to see if you have 120 volts across the heater/defrost thermostat combo.

I removed the interior panels from the freezer section. The coil was already icing up . I rotated the timer with a screwdriver and the fan and compressor turned off. The heater turned on. I would caution anyone who has never done this before: the heater is VERY HOT.

I rotated the timer to turn everything back on and now it is time to order the new timer.

This forum saved me a lot of money. Thanks so much.
